js实现广告拦截

// 假设广告元素的class包含'ad'
const ads = document.querySelectorAll('.ad');
ads.forEach(ad => ad.remove());

// 拦截XMLHttpRequest
const originalXHROpen = XMLHttpRequest.prototype.open;
XMLHttpRequest.prototype.open = function() {
    const url = arguments[1];
    if (url.includes('adserver.com')) { // 假设广告服务器的域名包含'adserver.com'
        console.log('Ad request blocked:', url);
        return;
    }
    originalXHROpen.apply(this, arguments);
};

// 拦截fetch请求
const originalFetch = window.fetch;
window.fetch = function() {
    const url = arguments[0];
    if (url.includes('adserver.com')) {
        console.log('Ad fetch blocked:', url);
        return Promise.resolve(new Response('', { status: 404 }));
    }
    return originalFetch.apply(this, arguments);
};
